REGISTER.

sPEoIFrcATIoN forming part of Letters raient No. 597,695, dated January 18, lees.A

Application filed April 18,1896. Serial No. 588,178.

To all whom t may concern: Be it known that I, WLLIAM G. SHAW, a subject of the Queen of England, residing at Buiialo, in the county of Erie and State of New 4York, have invented new and useful Improvements in Registers, of which thefollowing is a' specification. 1

This invention relates to that cla-ss of registers or indicators embodying a series of indicator wheels or disks which are 'arranged axially side by side.

The object of my invention is the production of a simple and durable register of this character which is-reliable in its operation and which can be manufactured at comparatively small cost.

In the accompanying drawings, Figure lis a longitudinal section of my improved register, which is particularly designed for use as a cyclometer. Fig. 2 is a transverse section thereof in line2 2, Fig. l. Fig. 3 is a perspective view ol' one of the indicator-wheels and the adjacent partition-disk. Fig. 4 is a perspective view of one of the pawls whereby motion is intermittently transmitted from one indicator-wheel to another. Fig. 5 is a fragmentary section' in line 5 5, Fig. 2, showing the pawl of one iudieator-wheelin engagement with a tooth of the next indicator-wheel Fig. 6 is a section in line 6 6, Fig. 5. Fig. 7 is a fragmentary section similar to liig. 5, showing the pawl of one indicator-wheel retracted out of engagement with the tooth of the next indicator-wheel. Fig. 8 is a section in line 8 S, Fig. '7. I

Like letters of reference refer to like parts in tbe several figures.

Although my register can be adapted for indicating the number of cycles of any moving body, I have shown the same arranged for indicating the number of revolutions of vbicycle-wheels and" will describe the sanrefin` this connection. l t

A represents a central arbor or rod which forms' thev support for vthe Working parts of the register and which is provided at one end with a iixed head 'a and at its opposite end with a removable head a', which is secured l wheel and which are with the partitions,

(No model.)

ofb the arbor by a screwbicyele-wheel is adapted to engage for turning the starting-wheel the extent of one tooth Aduring each revolution of the bicycle-wheel.

C C2 G3 C4 O5 O6 represent a series of stationary partitions or disks which are mounted side by side and axially in line on the arbor between the starting-wheel and the removable head and separated from each other and from said head and wheel, so as to form an intervening space between adjacent disks and between each of the end disks and the adjacent starting-wheel and removable arbor-head. Each of the partitions which Vis secured tothe arbor. The collar of each intermediate partition bears against the adjacent partition, while the outer ends of the collars on the outermost disks C C bear, respectively, against a shoulder c'on the arbor and the removable head of the arbor, thereby forming spacing-rings or washers, ,which hold the partitions in their proper relative position.

D D2 D3 I)4 D5 DG represent a number of indicator-wheels which register the number of revolutions which are made bythe bicyclearranged axially in line One of these indicatorwheels is arranged adjacent to the rear side of each partition and is provided with an inner sleeve d, which is mounted on the collar of the respective partition, and with an outerv which is provided on its ltherear head of the arbor, and the outer flanges of the indicator-wheels are iitted close is provided on its rear side with an inner annular flange or collar c,

together, as shown in Fig. l, thereby producing a compact construction. Each of the indicator-wheels is provided on its front side with an annular row of teeth c, one tooth beingprovided for and corresponding with each number on the periphery of its outer flange. Each of the partitions is provided with an opening e', arranged opposite the teeth of the adjacent indicator-wheel and cxtendingabout the length of one tooth.

F represents coupling pawls or catches whereby the starting-wheel and the indicator- 'wheels are coupled intermittently, sot-hat one of these members is compelled to move with the adjacent member during the extent of one tooth. One of these pawls is'secured to the rear side of `the starting-wheel.and each indicator-wheel, so that its annular path is in line with the opening in the adjacent partition. Each of these pawls is secured with its front or advancing end to the member which carries the same and is provided on its rear or trailing end with a hook f, which is adapted to project through the opening in the adjacent partition and vengage with one of the teeth of the next adjacent indicator-wheel for compelling. these two members to move together. The coupling-pawls are preferably made of spring metal, and each pawl is con` vstantly moved rearwardly away from the y member which carries the same toward the next rearward partition and indicator-wheel, so that the pawl upon reaching the opening in the partition will be moved through the same and into engagement with a tooth of.

the next rearward indicator-wheel.

G represents circular guide rails or flanges whereby the movement of the pawls is controlled. A pair of these rails is arranged on the front side of each partition on opposite sides of and concentric with the annular path of the pawl in front of the respective partitions. 'lhe guide-rails of each partition do not extend past the opening thereof, but terminate abruptly with their rear ends adjacent to the front end of said opening' and provided at their front ends, which are adjacent to the rear end of said opening, with inclines y. The coupling-pawl is provided on opposite sides with wings or lugs f', which are adapted to ride on the rails of the partition.

vDuring the idle portion of each revolution of the startinglwheel its pawl is held in a retracted position by the guide-rails of the partition C. lVhen the pawl reaches the rear end of the guide-rails and clears the latter during the intermittent forward movement of the starting-wheel, the pawl is projected through the opening in the partition C and engaged with the adjacent tooth of the indicator-wheel D', so that the latter is carried forward with the starting-wheel during the continued forward movement of the same.

After the indicator-wheel 1) has been moved forward the extent of one tooth the pawl is moved out of engagement with the tooth of said indicator-wheel and out of said opening by the guide-rails of the partition C2 and projected through the opening in the latter and into engagement with a-tooth on the indicator-wheel D2, whereby the latter is moved forwardly the extent of one tooth by the indica.- tor-wheel D. The indicator-wheel D2 is ,coupled with and nncoupled from the next indicator-wheel D3, so that the latter is moved forward the extent of one tooth during each complete revolution of the indicator-Wheel D2. Each of the remaining indicator-wheels is actuated one tooth at a time i1`1 like manner from the adjacent preceding indicator wheel during a complete revolution of the latter. The number of teethon each indicator-wheel and the corresponding numerals may be varied according to the desired kind l the foremost partition to the rear head of the arbor. This casing is provided with a longitudinal slot j, which is covered by a transparent plate j', and through which the registering-numbers of the several indicator-wheels are visible in a row. rlhe case is preferably made integrally with the foremost partition,

as shown in Fig. l, and the rear-arbor-head' is provided with an annular ange j2,'which vsurrounds the rear end of the case and holds the same in place.

I claim as my invention,- 1.' In a register, the combination with a circular partition provided with an opening and with a concentric guide-rail which projects from the side of the partition and extends from one side of said opening to the other side thereof, so as to form a gap between the ends of the rail adjacent to said opening, of two rotary members arranged on opposite sides of the partition, an annular row of teeth formed on one of the rotary members in line with the openingin the partition, a pawl mounted on the other rotary member and provided with a hook arranged in line with said'opening, and a lug projecting laterally from the side of the pawl and adapted to drop into the gap between the ends ofthe rail for permitting the hook of the pawl to pass through the opening in the partition and engage with said teeth and to ride upon said rail for disengaging the hook from the teeth, substantially as set forth.

2. In a register,'the combinationwith the partition provided with an'opening, of two rotary members arranged axially in line and on opposite sides of said partition, an annu- IOO IIO
